Conventionally, a package of this type with a continuous seal is known, for example, the structure disclosed in Japanese Utility Model Publication No. 53-32869. In this well-known sealed packaging, both the vertical seal and the horizontal seal are twill-shaped seals, and both of these seals are continuously formed by a pair of seal rolls.

In the conventional example, the sealing method is to sandwich a film sheet folded in two from both sides between a pair of seal rolls, heat-fuse the film sheets, and weld them together to form a seal. In order to form a twilled seal, the seal roll used has a jagged chevron-shaped surface, and these chevrons match with high dimensional accuracy between the pair of seal rolls, and this is achieved by applying a predetermined pressing force. If it is not pressed, it will not be possible to obtain a sealed package with an accurate and reliable seal. However, if the above-mentioned sealed package is something like a pouch, the chevron-shaped burrs (irregularities) in the twilled seal part are particularly minute, so the sealing work is carried out continuously at a considerable speed. It is extremely difficult to visually determine whether the unevenness of the seal part is accurate or not under the condition that the seal is in place.
Thereafter, the sealing pressure of both seal rolls had to be adjusted by inspecting the sealed package. Therefore, the drive of the apparatus must be stopped while this adjustment is being performed, resulting in a problem in that production efficiency is significantly reduced.

The actual sealing operation, which is the main part of the present invention, will be explained using the vertical seal rolls 5, 5 and the horizontal seal rolls 7, 7 described above. The film sheet 1 is fed using the conventional two-fold feeding device or means, and the vertical sealing portion 6 is continuously formed by the vertical sealing rolls 5, 5, and the horizontal sealing is performed by the horizontal sealing rolls 7, 7. Part 8 is performed intermittently. In this vertical seal portion 6, the lattice-like uneven seal portion 6a of a predetermined width and the solid seal portion 6b as described above are continuously formed. The sheet 1 is heated from both sides, and the low-temperature melting film 2 located on the inside melts and is pressed to adhere. Through this melting and pressing, the low-temperature melting film 2 on the inside is successively fused. However, the surplus is pushed out by the groove 16 and is transferred to the outer non-low temperature melting film 3.
The excess is pushed into the raised ridges 6c formed in the area, and the excess is absorbed as a whole, so the unreasonableness in the seal area is eliminated, and the seal base (content filling space 1
3), there is no damage, no pinholes are formed, and no wrinkles or folds that reduce the product value occur, and the entire seal is extremely strong. Furthermore, by forming the outer edge of the vertical seal portion 6 into a thin, recessed seal portion 6a, the sealed package b can be easily torn. Moreover, when the vertical seal part 6 consisting of the lattice-shaped uneven seal part 6a and the solid seal part 6b is formed continuously, the raised protrusions 6c are formed that are continuous in the vertical direction on the solid seal part 6b. By visually observing whether the protrusions 6c are formed in the correct shape, changes in the sealing pressure of the sealing roll can be immediately detected. In other words, the raised protrusion 6c
The vertical seal portion 6 is formed in a continuous manner, and is formed in a certain shape and form (protrusion dimension, width dimension, etc.) in advance by sealing roll pressure and heating when the vertical sealing rolls 5 are set. It is determined based on the temperature and material of the film, and its raised ridges 6
As c is continuously formed in the vertical direction, it is possible to immediately find out whether or not it is formed into the set shape or form just by visually observing it. If the shape or form is out of shape, the set shape or form can be achieved by making fine adjustments during the packaging process without stopping the driving of the device. In the illustrated embodiment, the raised convex strip 6c
is formed on both sides, but the same effect can be obtained even if it is formed on one side.Also, instead of visual observation, a sensor or the like is provided at the raised protrusion forming portion, and thereby the shape and form of the raised protrusion can be determined. It is also possible to make a judgment.

As explained above, the method for continuously sealing a sealed package formed from a laminated film according to the present invention involves feeding a laminated film sheet by folding it in half, and folding the overlapping ends of the film sheet in the longitudinal direction. In a method in which the outer edge is successively vertically sealed with a thin-walled lattice-shaped uneven seal part of a predetermined width and the inner edge is vertically sealed with a solid seal part of a predetermined width, and the solid seal part is horizontally sealed for each tightly sealed package, the solid seal part In addition, we have formed continuous raised protrusions in the vertical direction that allow you to visually see changes in the strength and weakness of the sealing pressure, so even during packaging operations, these raised protrusions allow you to check the strength of the sealing pressure at the sealing part. , the sealing pressure can be easily adjusted without stopping the drive of the reading device immediately upon a weak change, which has the excellent effect of allowing work to be carried out with high efficiency without reducing productivity. , the sealing device of the present invention feeds a laminated film sheet by folding it in half, and seals the overlapping ends of the film sheets along the length direction with a thin grid-like concavo-convex seal portion having a predetermined width on the outer edge. In a packaging device equipped with a seal roll that vertically seals the inner surface continuously in a solid seal portion of a predetermined width and horizontally seals each sealed package, the seal roll that performs the vertical sealing is provided with a lattice pattern of a predetermined width. A concave-convex seal portion forming surface and a solid seal portion forming surface having a predetermined width are provided, and a groove portion is provided on the solid seal portion forming surface to continuously form raised protrusions in the vertical direction so that changes in the strength and weakness of the sealing pressure can be visually observed. Because of this structure, the vertical seal can be formed in two types: the lattice-like uneven seal part and the solid seal part, and the solid seal part has raised protrusions formed in the vertical direction, and the raised protrusions serve as reinforcement for the seal part. At the same time, it also serves as a guide for changes in the strength and weakness of the sealing pressure, and even when the packaging equipment is in operation, the strength of the sealing pressure can be adjusted so that the raised protrusions are formed in the appropriate shape and form. This provides an excellent effect in that weak changes can be easily adjusted while visually observing the raised protrusions.
